The beginning of love is the will to let those we love be perfectly themselves, the resolution not to twist them to fit our own image. If in loving them we do not love what they are, but only their potential likeness to ourselves, then we do not love them: we only love the reflection of ourselves we find in them
Some birds are not meant to be caged, that's all. Their feathers are too bright, their songs too sweet and wild. So you let them go, or when you open the cage to feed them they somehow fly out past you. And the part of you that knows it was wrong to imprison them in the first place rejoices, but still, the place where you live is that much more drab and empty for their departure.
